What does Pennsylvania mean in Latin?

Pennsylvania doesn't have a direct Latin translation. It's a combination of the Latin words "Penn" and "Sylvanis."

* Penn is derived from the surname of William Penn, the founder of the colony. It's not strictly Latin, but it's a Latinized version of the English surname "Penn."

* Sylvanis is a Latin word meaning "woods" or "forest."

So, while not a true Latin phrase, the meaning of Pennsylvania is essentially "Penn's Woods".
